Bad. Flight was delayed due to maintenance issue with Delta. Seats were small, no service, bag got broken on initial flight. Cramped and hot. Sitting inside with no ac.

Aircraft without problems that leave on time, not 2 hours late with last minute gate changes across the terminal

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

Delta flight was on time, seats were comfortable, and crew was nice.

Airline lost my luggage and set me back a day worth of travel due to having to stay in Denver to wait on my luggage

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

The flight attendants were friendly and seemed to like their jobs. I am not a high maintenance person, but they seemed to respond to people's needs and requests in a timely fashion with a smile.. I appreciate the benefits of complimentary snacks and beverages, as well as the relatively inexpensive checked baggage fee. (Although I would like it better if it were free! :) ) The only improvement that could be made to make the boarding process more efficient is to board the plane from the back. The alternative would be to board people with only a personal item first. This would reduce the wait time while others are stowing their baggage.

I’m leaving it really bothered me. My bag did not come in on time and I had medication in that bag that needed to be in the refrigerator and I still throw it out. Are you going to buy things because it came so late

The food and drinks were good. Other than that airplane cabin and bathrooms were dirty and airplane was HOT.

I did not like 2 3 2seating. The food quality was declining. The appetizers were good. But the main course was limited and I had to send back my lamb chop which was too dry. The meal before landing was disappointing and not appetizing.

Very good. As expected. Have used their service several times. Highly recommend

Again the lounge boarding process were the only flaws. I was sitting comfortably in the overcrowded , under-catered business lounge at IST and got a notification in my phone that boarding had started. I rushed to the gate only to stand there an additional 5 minutes before boarding actually began. I could have enjoyed additional time in the lounge. At least they clearly separated business and economy classes in the boarding area so it wasn’t a total mob scene.

waited standing in security corral for an hour with no updates

Food was surprisingly good for airplane, crew was great, though announcements were sometimes hard to hear. Plane was nice (had great headroom, large screens and big dimmable windows). But seats were uncomfortable in economy (seat width was fine, but not enough shoulder room). I wish I could use my person Bluetooth headphones with screen( I think I could mirror it on my device, but didn’t want to keep tray table down to hold it up).

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

Same as before boarding process and lack of crew experience in the process

Excellent service. Made United 's business class look like a cattle car

The flight was canceled. It was very troubling because the rescheduled to Air France was two days later. I incurred two days extra of hotel, was not able to get a boarding pass until I reach the boarding desk at the airline. I don’t know what happened British Airways, but I was very disappointed.

I can't believe you have to pay L 3.20 for a Cup of British tea on an airlines with the name British on the plane.

Was very bad the cancel the flight after when we arrived to London

They lost my baggage and still waiting an update when I can receive it

American Airlines is the worst airline to fly. you can’t get on an earlier flight if you don’t have ‘status’, they cancel their flights with no warning, and they lie about why their flights are delayed so they don’t have to pay for meals or hotels. They lost me as a customer after this trip. I’ll be flying Delta or Untied from now on.

The checkin process is always horrendous with this airline. They never have enough people working the desk or people assisting in the lines. Rude and unbothered. I never pick British Airways- I always get swapped in via American Airlines and may need to stop using American Airlines as well. No entertainment in flight. And they seem more concerned about selling food and drinks then they are about customer comfort

Late from Istanbul. Canceled my seat to NY in London although I've been on time for boarding. Didn't provide with hotel and shuttle, no food, just sleeping and hygiene bag. Hope, they will refund me.

Terrible service. Stewardess behavior horrible. No sense of customer service. Seats were small, in general very bad experience which is not the case for me on other international flights via BA

Great!!! The first flight was a little painful because the chair wasn’t reclining and my back was destroyed by the time I got in London. But the second flight was perfect!! Super comfortable, the food was amazing, the crew super polite and helpful. Overall, I had a good experience

TIRED OLD plane. Seat cushion is completely old and NOT cushion at all; after an hour of flying butt hurts. Boarding is a complete disaster. No one respects the boarding groups, and the BA boarding crew care less about boarding groups or Tier status. What is the point of spending all this money on Business Class tickets when no one respects the boarding system? It took 90 minutes since we landed to get our luggage. 20 minutes to show on the screen which belt we are supposed to go to and another 1 hour to get our luggage - not the kind of service you will expect from BA at LHR
